I am searching for my gggrandfather Peter Rioth and his daughter Lina(Magdalena) who came to the US from Germany probably between 1883 and 1887 to Queens NY. I understand that at this time they probably came thru Castlegarden - I can't find either of them - I have searched under every spelling variation of the last name I can think of - and cant find them? Any suggestions ? If they had family here is it possible they wouldn't have come thru Castlegarden - but I can't find them on any manifest. Any help is appreciated.
